Did you consider automating it at all though? I've been considering using Companies House data, and a web-scraper, to find tech companies in my local area.
Oh, companies house is a good one. I would have a look, but I would be wary as I can see traps; for instance the legal office address registered at Companies House might not be the actual office address you should go to for an event or an interview.
But generally I do like automation, as long as we can get high quality results.
I was presuming the legal office address was going to be their accountant's address too. However, if you get a name from Companies House, you might be able to find a website, and then a contact page... It might turn into a hard NLP problem though :)
The companies house data should be useful in that the company name is different for companies registered in scotland (Starts with SC) compared to those started in england and wales which just have a number.
I'd say there's probably a big correlation between that and companies operating primarily in Scotland as there's no major difference in terms of tax etc (for now) on where companies are registered, so no incentive to put in an artificial registration.
